Abstract | BACKGROUND: OBJECTIVE: METHODS: This was a multicenter, randomized, double-blind, placebo-controlled study. After a 3- to 21-day placebo run-in, 677 patients aged 12 to 81 years were randomized to receive 0.4% or 0.6% olopatadine or placebo, 2 sprays per nostril twice daily for 2 weeks. Patients evaluated morning and evening reflective and instantaneous nasal symptoms ( sneezing, stuffy nose, runny nose, and itchy nose, which compose the total nasal symptom score [TNSS]) and ocular symptoms. RESULTS:
Olopatadine spray (0.4% and 0.6%) was statistically significantly superior to placebo for percentage change from baseline in overall reflective and instantaneous TNSSs. Also, 0.6% olopatadine was statistically significantly superior to placebo for reducing the reflective and instantaneous assessments of sneezing, runny nose, itchy nose, stuffy nose, itchy eyes, and watery eyes. Olopatadine spray exhibited a safety profile comparable with that of placebo. CONCLUSIONS:
Olopatadine nasal spray (0.4% and 0.6%) provided statistically significant improvements in allergic rhinitis symptoms compared with placebo regarding TNSSs and individual symptoms, including congestion, itchy and runny nose, sneezing, and itchy and watery eyes, in patients with SAR to mountain cedar. Olopatadine nasal spray administered twice daily was safe and well tolerated in adolescents and adults.
